What information on the periodic table is used to complete electron dot diagrams?

The number of valence electron information on the periodic table is used to complete electron dot diagrams. One can obtain the number of valence electron information on the periodic table by determining the column number of the periodic table. The first column number has 1 as the number of its number of valence electron and so on.

This is what i found on google “what happens to the bond angle when you add or remove an electron domain? the bond angle decreases as you add domains 5. can you force the atoms into new configurations by pushing atoms around? note: we can think of a bond or a lone pair of electrons as a “domain” of electrons.” i hope this you
